NOTICE OF PREI' R.vHON OF ENVmoN,vlEN I AI. IMPACT RE:PURI <br /> TANC TRANSMISSION PROJECT PAGE 9 <br /> Environmental Issue <br /> Area Potential Issues or impacts <br /> equipment or other vehicles during construction, operation, or maintenance activities. <br /> Impacts from the inadvertent uncovering of hazardous materials during excavation <br /> activities, causing toxic releases to the environment. <br /> Construction vehicles would require on -site refueling, and may require routine or <br /> emergency maintenance that could result in the release of oil, diesel fuel, transmission <br /> fluid or other materials. <br /> Fire hazards during construction by workers and equipment use, and during TTP <br /> operation through the contact of transmission line with vegetation. <br /> Hydrology Impacts from increased surface water runoff, erosion, siltation, and sedimentation. <br /> and Water Quality Impacts to streams or washes from violation of water quality standards or waste discharge <br /> requirements. <br /> Impacts to groundwater recharge resulting from creation of impermeable surfaces. <br /> l lydrological impacts to creeks and rivers and flood control channels. <br /> Land Use and Conflicts with applicable federal, State, and local land use plans, policies, or regulations <br /> Recreation adopted for the purpose of avoiding or mitigating an environmental effect. <br /> Impacts to residential, recreational, commercial, and transportation corridor land uses <br /> resulting from disruption, impedance, or removal of existing and planned land uses. <br /> Impacts resulting from reduced access to recreation areas during construction <br /> activities. <br /> Noise On -site noise during construction primarily from heavy -duty diesel and gasoline <br /> powered construction equipment. <br /> Off-site noise generated from trucks delivering materials and equipment to the job <br /> sites, as well as from vehicles used by workers commuting to and from the job sites. <br /> Operational noise as a result of corona noise discharge from active electrical lines. <br /> noise generated from substation activities, and noise generated from maintenance <br /> activities. <br /> On -site groundborne vibration and groundborne noise during construction primarily <br /> from heavy -duty diesel and gasoline- powered construction equipment. <br /> Off -site groundborne vibration and groundborne noise generated from trucks <br /> delivering materials and equipment to the job-sites. <br /> Impacts from both construction and operational noise activities violating local noise <br /> ordinances (volume and hours of operation). <br /> Public Services Impacts from increased usage of public resources, services, and utilities. <br /> and Utilities Impacts to emergency access and response times resulting from construction activities. <br /> Impacts from increased generation of waste and disposal needs. <br /> Socioeconomics Impacts from the employment of construction personnel during construction of the <br /> TTP to established and projected population, housing, and employment levels within <br /> the project area. <br /> Potential positive fiscal impacts in property- taxing jurisdictions, which would receive tax <br /> revenues from the TTP. <br /> Impacts to property values of parcels crossed by or near the TTP. <br /> Disproportionate impacts on low- income and/or minority populations <br /> Transportation Temporary disruption of traffic flow, transit services, or rail services during <br /> and Traffic construction activities. <br /> Physical impacts to public roadway rights of way (i.e., lane closures, detours, driveway <br /> blockages, loss of parking, and disruptions to traffic, transit, and pedestrian <br /> movements in the construction area). <br /> Other Issues Cumulative Impacts (considering other projects that are planned, proposed, or under <br /> construction in the project area) <br /> Growth- Inducing Effects <br />
